Simultaneous extraction of fat soluble vitamins (A, D, E and K) from serum presents a number of challenges, from the diversity of molecular structures and properties, to the wide variation in relevant clinical concentrations. Biotage specialists developed a method based on the Supported Liquid Extraction technique that effectively addresses these challenges.
Over the last 20 years, renewed scientific interest in the functions of Vitamin D in the body have required the development of sensitive methods for extraction and analysis of its various metabolites. Our specialists have developed the following application notes to deliver high analyte recoveries and clean extracts from serum.
Protocol for the extraction of 1,25 di-OH Vitamin D metabolites from serum using supported liquid extraction prior to LC-MS/MS detection.
Simple, effective protocol for the extraction of 25-hydroxy vitamin D from serum, demonstrating high, reproducible analyte recoveries with low protein and phospholipid content in the extracts.
Supported Liquid Extraction plates and columns designed to provide high analyte recoveries, and clean, protein and phospholipid free extracts. Methods are easy to develop, and automation is simple.
